1. WELCOME FROM Ireland

2. The History of Evaporative Cooling Evaporative cooling is the oldest form of air conditioning ever used The ancient Greeks used to fill terracotta pots full of water and leave them by doors and windows to benefit from evaporative cooling The Arabs hung wet blankets over doors and windows to achieve the same effect

3. The physics of evaporative cooling Evaporative cooling is a natural phenomenon that occurs when moving air passes over a wetted medium or water source, i.e. fountain, river, sea, shower, etc. The human body uses evaporative cooling through sweating to maintain a constant body temperature.

4. The physics of evaporative cooling Warm dry air when passing over water liberates some of the water in the form of an evaporate. This adiabatic process converts sensible heat (that which can be measured by a thermometer) into latent heat.

5. The physics of evaporative cooling The net result is air which has measurably lower temperatures than ambient air (approximately 6-7 o C for typical Irish summer temperatures) but has increased levels of relative humidity
